PLOW-STANDARD.

SPECIFICATION forming part of Letters Patent No. 246,496, dated August30, 1881.

Application led April 19, 1881. (No model.)

To all whom it may concern Be it known that I, IsAAc R. GILBERT, ot'Charlestown, in the county of Clark and State ot' Indiana, have inventedcertain new and useful Improvements in Plow-Standards; and I do herebydeclare that the following is a full, clear, and exact descriptionthereof, reference being had to the accompanying drawings, and to theletters of reference marked thereon, which form a part of thisspecification.

The nat-ure ofthis invention relates to a plow in which the standard isadapted to be provided with either a shovel-blade, a cottonscraperblade, a cotton-sweep blade, a bulltongue blade, ora turning-plowbottom. These devices are detachably secured to the standard, and fromtheir construction and the object for which they are employed requirethe standard to be set at dieren't angles with respect to the plow-beamin order to vary the pitch ofthe attached blade.

The object of my improvement therefore is to provide means for readilyadjusting the standard to the angle requisite to give the proper pitchto the blade which it carries. To attain this object I pivot the upperend ofthe standard to the plow-beam, and to a sliding block adjust-ablyconnected with the beam l pivot an inclined bra-ce thatis hinged to thestandard, as hereinafterdescri bed and claimed.

ln the annexed drawings, Figure l isa bottom perspective view ot' myinvention, and Fig. 2 is a longitudinal section taken on a Verticalplane through the same.

A indicates the plow-beam; and B the slotted standard, which is adaptedto receive various kinds of plow-blades, said blades being bolted to thestandard as usual. The standard is hinged to the beam so thatit can beswung backward or forward as occasion may require.

l) indicates the inclined brace that is arranged at the rear ofthestandard. This brace is hinged or pivoted in the slotted standard, andis also hinged to a sliding block or plate,

E, by means ot' a pivot, e, passing through lugs e e', that are formedupon said plate or block. This plate or block can be moved backward orforward along the under side ot' the beam in order to vary the angle of'the standard, and hence determine the pitch ofthe blade carried thereby.To hold this sliding plate to the beam, and also to secure it in itsadjustment, I form it with a slot,f, through which a bolt passes, saidbolt also passing th rough the beam and being secured thereto. Upon thelower screw-threaded end ot' this bolt is arranged a nut, I, which notonly serves to hold the sliding plate in contact with the beam, butwhich, when tightened up against the slotted plate or block, secures thesame in place.

It is obvious that a metal plate could be secured to the beam and asetscrew passed through the slot of the sliding plate into the platethat is held rigid with the beam.

I am well aware that various means have been used for adjusting'plow-standards to dit'- ferent angles, and among them an angular brace,one end ot' which is pivoted to the standard andthe other provided witha slotted plate, by means ot' which it is bolted to the beam. Such anarrangement fails to eii'eot pertect results, as I nd it absolutelynecessary to pivot or hinge the brace not only to the standard,

but also to a sliding block, in order to admit of the`block sliding on aline parallel with the under side of the beam, and thus enabling thebrace to be easily set at any desired angle and quickly secured in anygiven position.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, 1s-

The combination, with a plow-beam and a sliding block formed with a slotand lugs, as described, ot' a slotted standard and an inclined brace,said brace being' pivoted to the standard and block, all constructed andarranged to operate as herein set forth.

In testimony that I claim the foregoing as my own I at'x my signature inpresence of two witnesses.
